Mac Hica E3071
AWS E Co Cr-C
Descriptions & Applications:
Grade 1 stellite type high recovery cobalt based electrode designed to combat all four elements of wear, i.e. heat, impact, corrosion and abrasion. Most suitable of cobalt range where abrasion is the most predominant of the four elements of wear. Excellent for rebuilding corners with minimum base metal dilution. Has ability to overlay extensive areas without cracking. Will retain hardness at high temperatures. Welds are non-machinable. Recommended for use in the iron and steel industries or any industry where heat, corrosion and abrasion occur concurrently.
